ABSTRACT:
The present invention relates to an apparatus and method for controlling output power of a combination hood and microwave oven, and more particularly, to an apparatus and method for controlling power of a combination hood and microwave oven, wherein an output level of a high voltage transformer for generating a high voltage can be adjusted. According to the combination hood and microwave oven of the present invention, the electric power supplied to the high voltage transformer can be increased by temporarily turning off the parts (limited to the components which can be controlled separately from the microwave oven function), such as the vent fan or the electric indicator lamp, having large power consumption. Thus, the output power level thereof can be increased. Therefore, there are advantages in that the quick cooking can be made and cooking performance can be improved due to the high output of the transformer, when the user intends to make the quick cooking with the high output power.
